Struct Deadline 

pub struct Deadline { /* private fields */ }

Per-run wall-clock ceiling for the compute phases.

The timeout parameter only ever reached git subprocesses (set_git_timeout); the native CLI is protected by a process-level watchdog that exits 124, but the library path — pyo3, and through it the MCP server — had no ceiling at all: a 420s timeout was observed to sit through an 8-minute edge build without firing.

A per-run value rather than a process global (#210): the MCP server runs overlapping pipelines on worker threads, and a shared atomic meant the last request to arrive overwrote every in-flight request’s ceiling — and an expired ceiling was never cleared, so unrelated later runs in the same process (the yaml harness above all) inherited it.

Expiry panics with a recognizable message on purpose: the phase runs deep inside call chains that do not return Result, rayon propagates the unwind to the caller, and pyo3 surfaces it as a Python exception — an error after timeout seconds, where before there was a hang.

Implementations

impl Deadline

pub fn from_timeout_secs(timeout_secs: u64) -> Self

Saturating: an absurd caller-supplied timeout must clamp to “no ceiling”, not wrap behind now and fire instantly.

pub fn none() -> Self

pub fn check(&self, phase: &str)

pub fn enter(&self) -> ScopedDeadline

Publishes this deadline to the current thread for the guard’s lifetime, so hot loops deep inside edge builders can poll it via check_current_every without threading a parameter through 51 EdgeBuilder::build implementations. Each rayon worker publishes its own copy, so concurrent runs never see each other’s ceiling.

Trait Implementations

impl Clone for Deadline

fn clone(&self) -> Deadline

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Deadline

impl Debug for Deadline

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
